How to parse link url from a tag with sfref?

I am trying to scrape website data and I can look for a tags that I want to explore.
However, this tags are like <a title="Annex" href="https://www.myite.com/d…-3.pdf?sfvrsn=b3a84558_2" sfref="[documents|librariesProv…-4ef8-8b90-ae20b6b7590d">
getting a.href just returns https://www.myite.com/d…-3.pdf?sfvrsn=b3a84558_2 and that results in 404 page.
However, when I click on the tag on web page it opens pdf - the url is slightly modified.
How to handle these types of links in javascript. I am using js fetch similar to this post.
Thanks in advance.

sfref is an attribute that is used to resolve dynamic links. For example, when the a tag is cliked, the sfref attribute value is used to build href on the fly.
I assume you do not have the access to the logic used for link resolution.
The best thing you can do here is to tuse Chrome Dev Tools -> Event Listeners and find out the event where the link resolution happens.
Please keep in mind that different a tags might have a different resolution logic attached to them.

Render HTML with page breaks in browser

I have dynamic HTML generated based on user entered content. I want to show that HTML as A4 pages. The content may span to any number of pages as it is continous.
A code pen like this one https://codepen.io/rafaelcastrocouto/pen/LFAes helps how to show html as A4 pages. This is quite good but my problem is that I don't know in advance how much content one page can have. Will the content be rendered in first page tag or two page tags or more, I don't know since this is user generated content.
<page size="A4">
<!-----Dynamic HTML comes here, can confine to this page or overflow out of that---->
</page>
How do I show html structured into multiple pages in this scenario?
I know a hint that it might be possible with use of Javascript or query to create multiple page tags and place html chunks inside that but I would prefer CSS way of doing it as JS mechanism is susceptible to inaccuracies due to calculation of heights.
Is that possible?
Also how about using page-break-before and page-break-after property of CSS. I have used that property but that renders only in PDF, I want to show that in HTML in browser, is that possible with that?

Trouble inserting a javascript variable into an HTML tag [duplicate]

I want to add twitter card meta tags to my website. i cannot add static tags since the content attribute in the meta tag has to change dynamically.
Plz help if someone has a solution.

You can't, at least not in any way that Twitter is going to recognise.
When Twitter fetches the page, it is always going to get the meta elements that are in the HTML, never ones added with client side JavaScript.
If you are changing content dynamically then make use of the history API to update the URI, and make sure that the server will generate all the content for each URI when the URI is used as an entry point (you can still use JavaScript to generate the content when moving from another page on the site).

You can generate pages dynamically (server side) as long as you don't intend to change them after. Think about the process in the same way you would build landing pages for SEO purposes. Twitterbot is in many ways really similar to Googlebot and similar indexers.
See https://dev.twitter.com/blog/twitter-cards-tips-tricks for a few examples of sites doing this.

cURL returns full HTML via AJAX - how to display to user?

I am building a Wordpress plugin to display a list of jobs to a user pulled from a recruiting platform API. On click of a job, a cURL request is sent to the API that pulls the job details as a full HTML page (the online job advertisement). I have everything working fine in terms of pulling the HTML, but I cannot figure out how to display it to the user.
How can I either:
Open a new tab to display the HTML pulled from the AJAX request
or
Open the full HTML within a div on the same page (i.e. a modal)
I would prefer to open the HTML in a new page, but don't know how to use jQuery to do this... Opening within the page in a modal is also fine, but as far as I understand iFrames (which I would rather not use anyway), you have to pass a url (and I simply have the full markup). Is there a way to display this within a page, perhaps using canvas? It carries its own links to CSS and Javascript that need to apply only within that sub-page.
EDIT:
As a clarification, I know that I can simply place the HTML within the page. My issue is that it is a full page. This means it has a <head> <body>, and its own CSS links. Just putting it in the page messes with the rest of the CSS and produces invalid HTML.
This is what I already have:
$.post(ajaxurl, data, function(response) {
$('.sg-jobad-full').html(response);
});
It places the response within the page perfectly well... but it messes up the page by introducing a <body> within a <body> and competing CSS.

If you put the response in a <div>, it will mess the markup because css/js/meta definitions may not be put into the <body>.
If there is a way to retrieve the data without the markup already beeing in, you could parse the data and let it print via a javascript, which is the method I'd prefere.
According to your comment, you should really go with iframes, all other methods will alter your markup to have <html> tags inside <html>, which is very bad practice.
Iframes can be styled just like a <div> element, and it is realy not dirty to use iframes for the purpose you mentioned (it does not load from a foreign host, it is not hidden, it does not track).
<iframe class="job-offers-plugin" src=".../wp-content/plugins/yourplugin/getJobs.php">
</iframe>
Put some style into it like width;height;padding;margin;overflow; place it where you like..

Using WPDB in standalone script?
Add permalinks to your plugin script:

If you get the full HTML in an jQuery.ajax(...) call, you can always just show it in a certain div on your page.
$.ajax({
success: function (resp){
// resp should be your html code
$("#div").html(resp);
}
});
You can use the $(selector).html(htmlCode) everywhere you want. You can insert it into modals, divs, new pages...
If you have to inject a whole HTML page you can:
strip the tags you don't need
or
use an iframe and write the content to that iframe: How to set HTML content into an iframe
iframes aren't my favourite thing... but it's a possibility

Load pages via AJAX and execute javascript and CSS

I've been searching for a while now, but I can't figure out how to load an entire page via AJAX and still execute all javascript and css.
Mostly I just end up with the plain text without any CSS.
Is there a way to do this? I tried jQuery.get, jQuery.load and jQuery.ajax, but none really work like that.

I have a different solution. You may try it with an iframe. Use jQuery to append an iframe script including all relevant codes into some part of your page (like some div). This may do it for you including CSS, like;
$('<iframe src="your_page.html"/>').appendTo('#your_div');
Or you may try something like;
$('<iframe src="your_page.html"/>').load(function(){
alert('the iframe is done loading');
}).appendTo('#your_div');

I have solved similar problem as following.
Download the webpage over ajax
Iterate it over and find any <script> and </script> tags
Get content from within these tags as text
Create new <script> element and insert there the code
Append the tag to your webpage
Another thing is you will need to somehow call the script..
I have done it this way:
I set standardized function names like initAddedScript callback which I am calling after appending the script to the page. Same as I have deinitScript called when I do not need the code (and its variables,..) anymore.
I must say this is awful solution, which likely means you have bad application architecture so as I have had:)
With css is it the same, but you do not need any handlers. Just append the style tag to your documents head.

If the page you load doesn't have any style data, then the external stylesheets must have relative paths that are not correct relative to the invoking document. Remember, this isn't an iFrame - you aren't framing an external document in your document, you're combining one document into another.
Another problem is that loading your complete page will also load the doctype, html, head, and body tags - which modern browsers will cope with most of the time, but the results are undefined because it's not valid HTML to jam one document into another wholesale. And this brings me to the third reason why it won't work: CSS links outside of the head section aren't valid, and the misplaced head section caused by your haphazard document-in-document collage.
What I'd do for compliance (and correct rendering) is this, which would be implemented in the Success callback:
Copy all link elements to a new jQuery element.
Copy the contents of all script in the head section
Copy the .html() contents from the loaded document's body tag
Append the link elements (copied out in step 1) to your host document's head
Create a new script tag with your copied script contents and stick it in the head too
Done!
Complicated? Kind of, I guess, but if you really want to load an entire page using AJAX it's your only option. It's also going to cause problems with the page's JavaScript no matter what you do, particularly code that's supposed to run during the initial load. There's nothing you can do about this. If it's a problem, you need to either rewrite the source page to be more load-friendly or you could figure out how to make an iFrame suit your needs.
It's also worth considering whether it'd work to just load your external CSS in the host document in the first place.

I suppose you are looking for something like this:
your page div --> load --> www.some-site.com
After a quik search the closest solution seems to be the one by "And": Load website into DIV
You have to run a web server and create a proxy.php page with this content:
Then your JQuery load() function should be like this:
$("#your_div_id").load("proxy.php?url=http://some-site.com");
NB. I have tested this solution and it should not load all the CSS from the target page, probably you'll have to recreate them. For example the image files stored on the remote server will not loaded, I suppose due to authentication policy.
You will be also able to view only the target page without the possibility to browse the target site.
Anyway I hope this could be a step forward to your solution.

Get your entire webpage as text using ajax
document.open();
document.write(this.responseText);
document.close();
OR
document.documentElement.outerHTML = this.responseText;
But you need to change the path of css and js pages in original webpage if the resulting webpage is in another directory.
